Latest 3G Standard Release
Well i am newbie to telecommunications could someone clarify something for me:
- the current 3G release, of which i was taught a fast paced R8 edition i have seen something like R9 but haven't read it in particular
- the current downlink and uplink speeds
- the radio technology "UTRAN" (which has lead to EUTRAN)
- the main codec used whether its W-CDMA\CDMA what is HSPA+ is? whether MIMO (2*2 , 4*4) or Smart Antennas are used under UTRAN or its still the normal sector, omni-directional or direct antenna being used.
the advice on this matter would be of grateful knowledge to me and other

I guess this can set the discussion in the right way! Based on 3GPP and 3GPP2
- General Packet Radio Service (GPRS) offered speeds up to 114 Kbps.
- Enhanced Data Rates for Global Evolution (EDGE) reached up to 384 Kbps.
- UMTS Wideband CDMA (WCDMA) offered downlink speeds up to 1.92 Mbps.
- High Speed Downlink Packet Access (HSDPA) boosted the downlink to 14Mbps.
- LTE Evolved UMTS Terrestrial Radio Access (E-UTRA) is aiming for 100 Mbps.
|
- One Times Radio Transmission Technology (1xRTT) offered speeds up to 144 Kbps.
- Evolution Data Optimized (EV-DO) increased downlink speeds up to 2.4 Mbps.
- EV-DO Rev. A boosted downlink peak speed to 3.1 Mbps and reduced latency.
- EV-DO Rev. B can use 2 to 15 channels, with each downlink peaking at 4.9 Mbps.
- Ultra Mobile Broadband (UMB) was slated to reach 288 Mbps on the downlink.
